摘要: A two dimensional periodic pattern of capacitive and inductive elements (12, 14) defined in the surface a metal sheet are provided by plurality conductive patches (62) each connected to back plane (30) between which an insulating dielectric (26) is disposed. The act suppress currents them. In particular, array forms ground mesh (24) for use combination with antenna. performance characterized frequency band within no substantial able propagate along mesh. Use such aircraft or other metallic vehicles thereby prevents radiation from antenna propagating skin vehicle. also reflects electromagnetic waves without phase shift that occurs on normal surface.
